This set featuring all Beethoven's 32 sonatas was released in 1970. 

This was the first time a Russian pianist recorded the complete set of the Beethoven piano sonatas. Three months before the pianist died, in 1978, a critic in the Sovetskaya Muzyka magazine called these recordings "a true feat of art".

She remains the only Soviet artist to have recorded the entire Beethoven piano sonata cycle and she gave herself the nickname of Maria Agressorovna and the end results are entirely Russian and a must have.
